In medium/high power applications including smart transformers, active power filters and wind turbines, parallel converters are a reliable solution to achieve low harmonic distortion, high efficiency and increased power handling. However, if such topology has a common dc-link source, the circulating current arises between the converters, increasing power losses of the switching components and propagating the stress of the dc-capacitors. This paper provides comparison of four most commonly used pulse-width modulation methods and their influence on the circulating current and the quality of the output current. The efficacy of the investigated method is validated by experiments.

The demand for high voltage, high power, high precision and high dynamic 3AC-voltage sources is increasing constantly. One application that gets more and more important in recent years and demands such voltage sources is e.g. Power-Hardware-in-the-Loop (PHIL) Emulation. In this paper a new power converter topology called “Parallel Hybrid Converter” or PHC is presented and a corresponding control scheme is derived. This new converter has a terminal behavior similar to a MMC or MMPMC but compared to them the PHC features significantly reduced costs and a significantly improved power density.

This article establishes a Constrained Finite Time Optimal Control (CFTOC) design for unknown, discrete-time systems with parametric uncertainty, whose dynamics are identified via Set-Membership Identification (SMI). The control scheme is composed of: a) the SMI module, which identifies the dynamics of the system through a Weighted Recursive Least Squares (WRLS) algorithm, and b) the CFTO controller, which can be online updated based on the SMI provided information, hence, providing the ability to adapt online the overall control framework based on the overall confidence intervals from the SMI. The proposed scheme has been adapted for the case of controlling a Vortex Actuator, based on an Electric Ducted Fan and utilized for wall climbing robotic applications. Simulation results are provided to demonstrate the efficacy of the overall proposed scheme.

Reliability has become a mandatory feature in many safety critical applications, where major accidents, equipment damage or expensive downtimes must be prevented. One of the major qualities of the switched reluctance motor (SRM) is its high fault tolerance features. Although this motor can be able to continue operating even with some of its phases disabled, in this situation it appears an important torque ripple that could affect its proper functioning in some applications. This paper presents a novel low cost spilt-winding fault-tolerant approach, together with the correspondent power converter, that enables the motor to continue normal operation in the case of a winding open circuit. The obtained results show that the proposed solution, and its inherent fault tolerance behavior does not present a huge impact on the overall motor efficiency.

This article proposes a modified control method to improve the bus voltage deviation and power sharing among the sources in multi bus DC microgrid. In DC Microgrid bus voltage regulation and load sharing between the sources is necessary for reliable and stable operation of system. The bus system in microgrid improves the reliability of overall system in case of bus failure. In the multi bus system, the line resistances and power flow in the system deviates the load bus voltage from its nominal value. It also affects the power sharing between the sources. The proposed control scheme overcomes the bus voltage deviation from its nominal value without affecting the power sharing among the sources. It also mitigates the power sharing mismatch because of unequal line resistances in multi bus system. The overall control is operated in distributed control with shared data from low bandwidth communication links. The designed control scheme balances the power flow within the DC microgrid along with energy storage system (ESS) operation. The proposed control scheme is verified in real time simulator.

This paper presents a novel control approach for a Dual Active Bridge (DAB) converter interconnecting a telecom isolated DC microgrid (IDCM) to a 380 V DC grid. A DAB converter is the ideal solution for this interconnection because it provides galvanic isolation, allows reversible power flow, and can operate with inherent soft switching, leading to high efficiency performance. The novel controller is based on Lyapunov's stability theory and adds integral terms to stabilize the IDCM nominal voltage. The new controller ensures the IDCM fast and stable transient response upon the connection of constant power loads (CPLs). In order to highlight the advantages of the new controller, comparisons using MATLAB/Simulink simulations are made with cascaded voltage/current linear controllers, their limitations being shown. Results point out that the novel controller is able to deal with the negative incremental resistance of CPLs, without the need of bulky stabilizing DC capacitors.

With the demand for greener urban mobility solutions, cities are implementing bike-sharing systems to reduce the usage of combustion engine vehicles and, at same time, promote physical activities. This concept presents itself as a good scenario to the implementation of wireless sensors network on bicycles due to its features: mobile transducers, different sensors and data, and system architecture. This paper discusses the scenario of an e-bike sharing infrastructure that implements a network of transducers following the guidelines from IEEE 1451 standards, highlighting the implementation its details. The development of network compliant with this family of standards promotes the implementation of features such as interoperability, connectivity, scalability, and plug-and-play on new devices and systems.
